MINERAL SAMPLER.

Specification of Letters Patent. Pate-3 4 6 -{a 2 1922 Application filed October 2, 1919. Serial no. 332,545.

T all/whom it may concern: Be it known that I, Gnonon F. DELAMA- ran a citizen of the United States, residing at teelton, in the county of Dauphin and State of Pennsylvania, have invented certain Improvements in Mineral Samplers, of which the following is a specification.

This invention is an automatic sampler adapted to be operated at regular intervals to segregate portions of the materials under examination by intersecting a flowing stream thereof. It is applicable to use for. sampling crushed coal, rock, ore, sand or other flowing solids, as also liquids that are not of such Viscous or adhesive character as to build up'in the apparatus. v

The objects attained by the invention are the 'desiderata of separating samples not only from the full cross section of a flowing stream, but also from a column falling vertically, with the segregation of representative samples, and the avoidance of the possibility of mixin thesamples with the main flow', b-y means that are simple and eflicient.

The invention is characterized by a'hollowbody or case provided withan inlet in the top thereof for the admission of a substantially vertical stream of materials whichare to be sampled, a throat (of substantially the width-of the body). adapted to oscillate across the inlet so as to fully intersect a stream flowing therethrough, a chute having an inlet below the bottom oft-he throat and an outlet through a side of the body, detachable wings connected with the sides of the throat at the top thereof and extending outwardly over the passage between the throat and the chute, and an outlet in the bottom of the body or case for discharging the main fiow of the material in process of sampling.

The characteristic features of the invention are embodied in the mechanism set out in the following description and the accompanying drawings in illustration thereof.

In the drawings, Fig. 1 is a side elevation of a samplerembodying my invention; Fig. 2 is a vertical sectional view thereof; Fig. 3 is a vertical sectional view taken on the line "---3 of Fig. 2; Fig. & is a side elevation of detached oscillating mechanism of modified form, and Fig. 5 is a sectional view taken on the line 5"5 of Fig. 4:.

The sampler, illustrated in Figs. 1 to 3 inclusive, comprises a hollow body or case 1 provided with a centrally disposed top inare,

6, with the respective trunion-s 7 and 8, which are journaled in bearings 9 and 10 supported by the body, the throat having a contracted bottom outlet 11. A chute 12, provided with the, angles 13, is supported in the body 1 by the angles 14 therein on which rest the angles 18. The chute has an open top adapted to receive the discharge from the bottom of the throat,

which oscillates therein, is provided with flared top members 15 for permitting the full swing of the throatwithin a limited width of chute, has its ends covered by the plates 5 and 6 extending downwardly from the throat and has an inclined outlet 16 extending through the side of the body.

l/Vings or aprons 17 are connected by their hooks 18 with the sides of the throat& at the top thereof, and are connected together by the parts 5 and 6 extending transversely thereto, the wings diverging downwardly. beyond the bottom of the throat and the top of the chute so that the inclined wing, di-

rectly below the inlet 2 will pass materials falling thereon beyond the chute. These plates 17, over which the bulk of the materials slides, are made detachable, in order that they may be replaced in case of. wear.

Inwardly inclined wings 19 extend across the sides of the body 1 above the ends of the throat 4 to cover the joints between such ends and body.

The throat 4, with the wings thereon, is oscillated at regular intervals, by any usual means applied to the shaft 7, through its full which is limited by contact of the bottom of the throat with the wings 15 at the top of the chute 12. The top of the oscillating throat passes transversely through the stream of the material, such as ore or coal, falling vertically thereto through the opening 2, and segregates a full cross sectional and characteristic part thereof, which is delivered through the bottom of the throat to the chute 12 and thence discharged by the outlet 16 through the side of the body 1.

As illustrated in Figs. 1 and 5, the oscillatory mechanism may be modified, so as to reduce the amount of the sample segregated at each oscillation, by reducing the inlet to V the top of the modified throat 4 by dividing its top as also the tops of the inclined wings 17 and providing intersecting inclined aux iliary' wings or aprons 17 in the notches 4:- and 17 formed thereby, these intersecting inclined planes 17 providing means for di verting part of the substance under treatment from the throat l and reducing the amount passing therethrough.

The case 1 is provided with the removable plate20 having the bearing 9 and the chute extension 2l thereo-n,the oscillatory mechanisin and the chute being removable from the case therewith.

Having described my invention, I claim: -1. In mechanism of the character de scribed, the combination with a case having an inlet in its top and an outlet in its bottom of a throat having an inlet of substantially the width of said inlet first named, means for oscillating said throat in said case to" cause its inlet to sweep across said inlet first named, ineans for discharging minerals from said throat through said case,and diverging wings carried by said throat, said w ngs adapted at the limits of their movements to" extend across said inlet first'named and intersect alternately the stream ot materials flowing therethroiigh.

2.1n mechanism of the character described, the combination with a case having top and bottom apertures, said case expand .ing from said apertures, of an oscillatory throat having an open topadapted to sweep across said top aperture so as to be out of registration therewith inclined plates extending oppositely from the topof said throat, so as tochute materials fromsaid top aperture to said bottom aperture and a chute to which said throat discharges, said plates covering the joint between said throat and chute. V

3. In mechanism of the character de scribed, the combination with a case havi-ng' a detachable side member, a top inlet and a -bottom outlet, or an oscillatory conduit in said case, said condu t having a bearing car ried by said member and removable from said case by detaching said member.

In mechanism of the character d'e-- scribed, the combination with a case having a detachable side member, a top inlet anda bottom outlet, of an oscillatory con'du'it and conduit, said aproiis bein g movablewith said 7 conduit alternately under said inlet first named so as to receive the materials 'passing therethrough.- j-
